SPRlNG-PRESSING MACHINE.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed September 18. 1906. Serial No. 335,074.

To all whom it may concern.-

Be it known that I, HARVEY E. SPANGLER, a citizen of the United. States,residing at Canton, in the county of Stark and State of Ohio, haveinvented new and useful Improvements in Spring-Pressing Machines, ofwhich the following is a specification.

This invention is a ortable-spring-fitting machine for making e lipticalvehicle or car springs, and operates to press together the leaves of thespring while hot by means of rollers carried in a frame and rolled alongthe edges of the leaves of the spring, pressure being ap lied upon therollers so that the leaves are ro led together evenly at all pointsalong their length. The pressure can be adjustably varied as desired.The implement also has rolls to guide and straighten the springleaves atthe sides thereof.

The device is illustrated in the accompanying drawings, in which- Figure1 is a side elevation. Fig. 2 is a side elevation at right angles toFig. 1. Fig. 3 is a vertical section on the line 3 3 of Fig. 2. Fig. 4is a cross-section on the line 4 4 of Fig. 2.

The frame of the machine consists of two side plates or branches 6,which are connected at the to by a cross-piece 7, integral with one ofthe si e pieces and joined to the other side plate by screws 8. Lowerdown the branches are braced and connected by cross-pieces 9, secured toopposite side edges thereof. The cross-plate 7 is tapped to receive thetube 10, which de ends therefrom between the sides 6. Slida ly mountedin this tube is a hollow plunger 11, which has a head 12, which slidesbetween a pair of extensions 13, projecting upwardly from thecross-plate 7. Mounted upon a pivot-bolt 14 between the ears orextensions 13, is a cam 15, formed with two branches bearing at oppositeedges of the head 12, and this cam has an o erating-lever 16. The camhas .a series of ho es 17, and the extensions 13 have several holes 18,and the throw of the cam may be varied by changing the pivot-pin 14 fromone holev to the other, The head has a stop 19, against which the handlestrikes when thrown over to prevent it from turning beyond center.

The lower end of the tubular plunger 11 bears upon the upper end of aheavy spring 20, coiled around a stem 21, the upper end of which fitswithin the plunger 11. The lower end of the stem is connected by abearingcollar 22 to an axle 23, which carries a pair of pressure-wheels24, arranged on opposite sides between the collar and the side plates 6.

The ends of the axle are guided and held in place by vertical slots 25in the side plates 6, and one end of said axle is provided with a crank26, whereby it may be turned. The faces of the wheels are beveled orfrustoconical, with the small ends inwardly. Mounted upon headed studs27 at the lower ends of the side plates 6 are two pairs of bottom rolls28, and just above these rolls are two pairs of side rolls 29, carriedin the forked inner ends of adjustable screwstuds 30.

In operation after the hot leaves are assembled the device described isrun thereon. The requisite pressure is then applied by means of the cam.Then by turning the crank 26 the device is run up and down along thework, the wheels 24 bearing on top and the rolls 28 underneath, and theside rolls 29 run along the edges of the spring to set the leaves upstraight. As stated, these side rolls may be adjusted in or out to suitwide or narrow springs. The frusto-conical faces of the wheels give themain pressure at the edges of the leaves, where it is needed.

The device has the advantage that the work may be clamped and heldstationary while the fitting implement is used, and the fittingoperation can be very quickly and easily performed.

I claim 1. In a spring-making machine, the combination with a framehaving opposite side plates and upper and lower pairs ofrollerssupported therein, between which the work is received, of adjustablescrew-studs in the side plates, and rollers carried by said studsbetween said upper and lower rollers, and adapted to bear against theedges of the spring.

2. In a spring-making machine, in combination, a frame, pairs of upperand lower rollers therein, the upper rollers being mounted upon an axleslidable up and down in the frame, a plunger and means to force the samedown toward the axle, and a spring between the plunger and the axle, tocushion the pressure.

3. In a spring-making machine, in combination, a frame, pairs of upperand lower rollers therein, the upper rollers being mounted upon an axleslidable up and down in the frame, a hollow plunger and means to forcethe same down toward the axle, a stem conaxle, and a can1-lever mountedin the frame and bearing against the plunger, to advance the same.

In testimony whereof I have signed my name to this specification in thepresence of 15 two subscribing witnesses.

nected at'one end to the axle and extending into the plunger at theother end, and a spring coiled around the'stem between the plunger andaXle.

5 4. In a spring-making machine, in combination, a frame, pairs of upperand lower rollers therein, the upper rollers being mount- 1 HARVEY E.SPANGLER. ed upon an axle slidable up and down in the Witnesses: frame,a plunger movable up and down in the LINA SPANGLER,
